Extremely flat cornea post-refractive surgery. No conventional lens will restore vision to this cornea. Only a scleral lens can restore this patient's vision.

Below is the same cornea more clearly showing post-lasik ectasia. 10 years after undergoing lasik, this eye developed hydrous which is caused by a break in the interior cellular layer of the cornea rupturing. The cornea has become porous as seen by the green dye in the anterior corneal tissues.
